Kihwal Lee commented on HADOOP-7445:
------------------------------------
+1
This is a minor point. Do you think we need to expose crc32c_sb8() and
crc32c_zlib_sb8()? If not, why don't we move these to bulk_crc32.c and get rid
of crc32.h? I thought the bulk verification API is all we need to make
available, but I may be wrong. If you believe it is better as is, that's fine
too.

> Once HADOOP-7444 is implemented ("bulk" API for checksums), good performance
> gains can be had by implementing bulk checksum operations using JNI. This
> JIRA is to add checksum support to the native libraries. Of course if native
> libs are not available, it will still fall back to the pure-Java
> implementations.
